I'll second Joe on this one.

I've had work done by Jon and his attention to detail is superb witih prices to match or beat any that I've seen.

I have also seen those Eidelon wedges and they really do look very nice. I would say that they are very reminiscent of a lot of the premium money Japanese wedges.

They look very interesting, specially the V-Sole design. The sole has minimum bounce, but the leading edge (1/4") has much higher bounce to stop it digging. This is meant to allow it to perform in a variety of shots, from tie lie fairways to bunkers and rough.

The face is meant to be CNC milled flat and then each individual groove is CNC milled to ensure consistent spin. Looks like it also features a spin milled face. Interestingly the standard shaft seems to be the steel Rifle Spinner, with the option of an exclusive Graphite Rifle Spinner shaft.

I noticed he also seems to deal with Wishon, so should be able to get hold of the Tom Wishon CX Micro wedges.  Supposedly Tom did some testing and found you get better spin with more smaller grooves in contact with the ball.

Jon's service superb.... he spined some shafts for me last summer, great turnaround speed and superb price ofr the work.

 i'd happily use his services again.

Interesting to see Jon's site.

I assume I would need to visit to do a dynamic test for loft and lie adjustments?

Not sure which wedges Sam was on about, but aggressive grooves can be found on many tour wedges. Tends to refer to U/Box/Square grooves that are machined with steeper and sharper edges (draft angle, edge radius, etc) for more bite and backspin. Where as normal grooves tend to get rounded and softened a bit during the chroming, sandblasting and polishing process. As mentioned, they do have a tendancy to shred the covers on premium golf balls (HX Tour, ProV1, etc), especially on full shots. Some are worse than others for shredding, although a session with range balls or bunker practice can break them in.

You can find aggressive grooves on retail wedges now also. Although maybe not to the degree of tour grooves, due to mass production and manufacturing tolerances.  Like Taylormade's Y-cutter grooves, Callaway's Mack Daddy (MD) grooves, Cleveland's Zip grooves, Titleist's Spin Milled, Sonartec's Yo-Yo Grooves etc.

Also smaller manufacturers can offer aggressive grooves on their wedges too, like Eidolon, Solus Golf, Scratch Golf, Tom Wishon, Fourteen Golf, Gauge Design, SMT Golf, Feel Golf, etc.
